SHERPA means, Screening for High Emission Reduction
Potentials on Air quality.
SHERPA aims to screen the space of all possible emission
abatement scenarios.

Scenario Assessment
Selection of:
- a region
- an Air Quality Index
- activity sectors or precursors
Concentration changes (i. e. Delta values)
HOW MUCH impacts?

Source Apportionment
Selection of:
- a region
- an Air Quality Index
- activity sectors or precursors
Average source apportionment for the selected region Average source apportionment for a selected point
WHAT can I influence? WHICH sectors/pollutants?

- a point
- an Air Quality Index
- activity sectors or precursors
Contribution per regions (the selected NUTS level)
WITH WHOM should I coordinate actions?
